PVTSO Battery Tests and Comparisons

PVTSO Battery Tests and Comparisons

We’ve tested a few of our PVTSO batteries against some of the best batteries out there to show you a performance comparison. As you’ll see from the graphs, the quality and performance of these batteries give Sony and Panasonic a run for their money!

For high-amperage testing, we tested each cell at 8A. This is a good amperage that any 18650 IMR should be able to handle, while also giving consistent results that apply to sub-ohm vaping. A battery at 3.7 volts pulling 8A of current means the resistance has to be 0.46Ω. Builds below this resistance will experience decreased battery life and voltage, while resistances above will have increased battery life and voltage. 8A is the perfect amperage for this test.

PV 1600mAh, 30A 18650 vs. Sony VTC3

We compared the PV 1600mAh, 30A 18650 against the Sony VTC3. You can see that the PV cell provided more voltage consistently throughout the test. This means that when used in a mechanical, this PV battery will further reduce your voltage drop and make your mod hit harder. The red line is the test for the LG 2500mAh, 20A battery. The jagged line just means that our testing equipment didn’t have a solid connection with the battery towards the end of the test. However, you can see that the PV battery beats both the VTC3 and the LG battery in terms of output voltage, and matches the VTC3 in battery life. This test was conducted with an amp draw of 8A.

PV Elite 2100mAh, 25A 18650 vs. Sony VTC4

We then compared the PV Elite 2100mAh, 25A battery to the Sony VTC4. By looking at the graph, you can tell that they are virtually identical, with the PV Elite even performing marginally better throughout the test. If you look at the very end of the graph, it appears as if the Sony VTC4 has better battery life. However, this difference is only apparent when the voltage is below 3 volts. Any VV/VW mod will not fire if your battery is below 3.2 to 3.3 volts. And mechanical users will be changing batteries around the 3.6 to 3.7 mark. So for all intents and purposes, the PV Elite will give you the same excellent performance and battery life as the VTC4, but with the added advantage of being able to find them for sale! These batteries were also tested with an 8A draw.

PV Elite 3100mAh, 10A 18650

Lastly, we tested the PV Elite 3100mAh, 10A cell by itself at a standard amp draw of approximately 20% of the mAh rating, or 0.63A. We thought 3100mAh for an IMR may have been too good to be true, but this battery actually exceeded our expectations, testing at 3112mAh! This battery outperformed the Panasonic 2900mAh cell by a wide margin. Not only that, but this battery lasts longer than most ICR cells, which are known and expected to have longer battery life at the expense of safety and the ability to handle high current. This cell is only intended for use up to 10A, and as such, is only recommended for use in VV/VW mods with an amp limit of 10A or less. So while this wouldn’t be a good battery for mechanical mods or high-wattage mods, like the iPV V2, it’s perfect for mods such as the Zmax, VTR, or even a DNA30 mod! This is the single-best IMR battery in terms of battery life.

From these tests, you can see that PVTSO batteries perform the same as or better than comparable well-known batteries. All tests were conducted with brand-new batteries that were precisely charged to exactly 4.20 volts.
